The analysis process adapted here can be applied when making population related decisions

Here, I linked 4 YouTube videos from my channel that can help you out
1 Country Boundaries
2 Population data
3 Utility location data
4 QGIS attribute tables
5. Zonal statistics

I performed an analysis of the Nigerian Railway system, to estimate how much of the population has convenient access to, at least, one railway station.

I'd love you to check out the documentation.

And then there's @myarmone ARM that you can't send a message except you're verified.

@calliypgianmel1 @piggyvest Omg I had a similar experience. Someone stole my SIM card, somehow got access to my email, and attempted to change my PiggyVest password.

I reached out and they acted swiftly. Even here on twitter, I’m constantly in their DMs.
I love them fr 😭

For my GIS guys, check out the video on how to style your street layers like the image in the opening tweet.

First time in Lagos, and I got a practical lesson in urban logic.

I was heading to No. 47, but to be safety-conscious, I entered No. 46 on the map and told the driver same.
Simple, right?
Wrong.

Turns out No. 46 and No. 47 were over 200 metres apart.
Why?

Another thing I genuinely loved: Many roads are named in native Yoruba (and other dialects). It’s a subtle but powerful way of preserving culture while navigating a modern city.
Small experiences like this remind you that cities have their own logic, stories, and identity.

@Aje_Dynamicz @Finaltoucch You mean using your account in multiple locations? Maybe multiple users?

@johnniecorp @TeedAnthony @supersanusi A fire hazard is not "poor anesthetics".
Do you see the joined wires all over the place?

Better to give up an additional battery with good installation that whatever is up there.

@ilovepdf_com

After all the love and affection we showed you, you added a pay wall.

@_Nosa_ Finally.. Long awaited!

Would be nice to have a notification reminder before the transaction time, for example: a day to a scheduled monthly transfer.

@OjiChioma1 One of my best topics in school!! 😭 Was so excited to watch.

Weldone.
Another contender was reduction formula. Loved it, passed it.

[map.dev @Fideliscleo]

@Ruizlex_0 Any reason why you preferred Google earth over QGIS? Or other desktop GIS?

[map.dev @Fideliscleo]

Lol. Deepseek just told me to use chatgpt to generate my script.

I used to defend this guy 😭 😂

Example:
-- To create a 100m buffer in a degree-based layer:
100 * 0.00000907 = 0.000907 degrees

Try it out! Ever used a similar trick? Share your thoughts below. 👇

📢 The Tiny Number That Unlocks GIS Analysis in Degrees (No Reprojection Needed!)

Have you ever struggled with performing distance-based analysis (like buffers or network routing) on data in geographic CRS (degrees)?

#GIS #QGIS #SpatialAnalysis #DataHacks #gischat

[map.dev @Fideliscleo]

The Hack:

After testing, I found that 1 degree == 111,319 meters at the equator. But for small-scale analyses, you can use:
~0.00000907 (or 9.07 × 10⁻⁶) as a scaling factor to convert degree-based distances to approximate meters in expressions.

@a__vanita @OlaniranEmmanu9 please are the ear pads replaceable?
